About UK fluid ounces per minute

The UK fluid ounce per minute (fl oz/min) equals 4.54609×10⁻³/160/60 ≈ 4.735×10⁻⁷ m³/s. It is found in pre-metric British plumbing and brewing specifications, where tap-flow and pump-delivery rates were stated in imperial fluid ounces per minute. A UK laboratory peristaltic pump calibrated to 30 fl oz/min delivers ≈14.2 mL/s. 1 UK fl oz/min ≈ 4.735×10⁻⁷ m³/s.

About US gallons per minute

The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
